'Appllcation'flled February e, 1918. Serial N0. 215,662.

To all whom it may concern- Be it known that I, OsoAR J. IV. GAEBE, a citizen of the United States, residing at Addieville, in the county of \Vashington and State of Illinois, have invented certain new and useful Improvements in an Autonatically-Operating' Control Switch for a Water System, ofwhi'ch the. following is a specification. T

This invention relates to a water pumping device and has for its object the production of a simple and efficient means forauto matically operating a supply pu1np,'when the water within a tank falls below the predetermined level.

Another object of this invention is the production of a simple and eflicient circuit closing means for automatically closing an electric circuit through an operating motor when the water within a tank falls below the predetermined level. I

With these and other objects in view this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the drawings z Figure 1 is a side elevation of the pumping system, the electrical wiring being shown in diagram,

Figure 2 is a vertical section through the water tank showing the circuit closing device carried thereby,

Figure 3 is a section taken on line 33 of Figure 2, I

y referring to the drawings, it will be seen that 1 designates the .main tank to which is connected an auxiliary tank 3 and a second tank 4: by means of the supply pipes 5 and 6. A pump 2 is placed adjacent the main tank 1 and a pipe 7 is connected to this pump 2 and overhangs the upper end of the main tank 1 as shown in Figure 1 for the purpose of supplying water to the main tank 1 from the pump 2. A main supply pipe 8 is connected to the pump 2 as shown clearly in Figure 1 of the drawing.

A motor 9 is placed to one side of the pump 2' and is connected therewith by means ofa shaft 10 for the purpose of driv ing the pump 2 as the motor 9 is operated.

The main tank 1 is provided with a laterally extending neck or pipe 11 which terminates in an upwardly extending end 12. An insulated float 13 is mounted within the upwardly extending end 12 of the neck or pipe 11 and a coil spring 1 1 is mounted withinthe upper end 12 and engages the top of the float 13 for urging the same downwardly. A plurality of contact points 15 are carried by this float 13 and are connected to the respective wires 16 and 17, the wires 16 and 17 being connected to the contact points 18 of the contact switch 19. Suitable supply wires 20 are connected to the switch 19 for the purpose of supplying current to the switch from a source of electrical supply. Suitable contact points 21 are carried by the contact switch 19 and wires 22 and 23 are connected to these contact points 21, the wires 22 and 23 being connected to the wires 24 and 25, which wires 24 and 25 are electrically connected with the motor 9. It should be understood that the contact switch 19 is. adapted to merely permit the electric circuit to the motor 9 to be manually closed when it is so desired, independently of the automatic switch above described. It of course should be understood that this electrical connection may be arranged in the ordinary manner wherein a contact switch is used.

The pipe or neck 11 carries an insulated block 26 which block carries a plurality of contact points 27 these contact points 27.

being electrically connected to the wires 24 and 25. The upwardly extending end 12 is preferably square in cross section for the purpose of holding the contact points 15 in a proper position to engage the contact points 27, the float 13 also being square and fitting snugly within the upwardly extending end12.

The contact points 15 are positioned in the inner ends of the sockets 15' formed in the float 13, in order to prevent the closing of a circuit between the contacts 15 and 27 by the liquid placed within the tank 1. When the liquid within the tank 1 falls below a predetermined point, the float will drop and the contact points 15 will close a circuit with the upper ends df these contact points 27 working in the sockets 15,

As shown in Figure 1, the tank 4 may be supported upon the supporting block 28 in order that the tank 4: may be supported at a proper elevation. It should be also under-' stood that the top of all of the tanks 1, 3, and 4 are arranged on the same level in order to prevent one tank from overflowing as the other tank is being filled.

As shown in Figure 2 of the drawings, the

contact points'27 are provided with an insulating'coating 15 to prevent the short circuiting through the medium of the liquid contained within" the'tank, but the upper 5" ends of these" points 27' are left bare so as: V through the operation of the automatic cirto contact with the contact points 15 car; ried by the plate which is supported'by the float 13. These contact points 27 are also insulated from the neck 11 and suitable conthe po-ints 27 as shewnin-Fig. 2. The operation o fthe lows: v V a Should the water within the tank 1 fall below the top ,face of the pipe 11, the coil spring 14 will shove or move the float 13 downwardly thereby forcing the contact pins 15 in engagement with the contact pins 27 for closing a circuit therethrough and operatingthe motor 9. As soon as the tank 1 is filled, the float 12 will be raised for moving the pins 15 out of engagement with the'pins 27, and in this way breaking the electrical ducting wires 2% and are connected to the motor 9. .v

' Should itvbe desired to empty the tank; 'for the purpose of cleaning or repairing the same, a suitable pipe or hose may be inserted in the tank 1 and suitable means attached 30 thereto for drawing the water from the tank.
